20 17 is too hot.

It is true that the weather in Shanghai is only summer and winter, either too cold or too hot, with almost no spring and autumn. It is late spring and early summer, and the temperature is like a roller coaster. It will be hotter and wetter in Huangmei in mid-June. However, this will not change the enthusiasm of Shanghainese for life and residence. Over the years, the permanent population of Shanghai has only increased.
